+p or +p+ 9mm load data

I asked this question because I was about to start ordering parts for a 9mm build.
I ordered a 10mm lower instead.
Thank you again for your time.

That sounds like a great idea. Which one did you get?
 
Have you thought of a barrel in 9x25mm Dillon. Works perfectly in the 10mm magazine.
Finding an in stock barrel is the hard part it seems. Have to have Clark etc make one from .38 super etc.
 
Seems like blowback is only option but I am going to look around for options before I buy the upper/barrel/bolt.

That isn't a deal breaker as long as you stay inside design parameters. Even with "book" loads you will be well above the power of an unsafe load in 9mm.
 
Depending on how many rounds you're intending to shoot why not just buy a few boxes of factory stuff? Federal, Speer and others make HST and Gold Dot loaded to +P pressure. And companies like Underwood load to +P and even +P+ levels.

In theory at least you'll be using ammo that's been pressure tested and safe.

black hog down:

I realize this is an old thread but I don't think your original question was adequately answered. I was wondering the same thing and after research did some testing as well.

The.lower risk option assuming one has a firearm rated for high pressure ammo a factory load such as the Federal +p+ 115gr HP or 9 BPLE tested at 1640 fps from a 16" barrel. Local law enforcement used this load in Smith 5906 handguns for years. 115 seems a bit light for hunting, however.

Reloading my own I reached that velocity with only 0.2 grains over the reloading manual max load for standard pressure ammo. I'm using a 16" PCC designed for +p ammo. Going further very slowly velocity rose to 1755 by 1.0 gr over standard maximum yet well well below my 9mm Major specs. No signs of pressure either visually or by measuring case dimensions. Sizing resistance didn't change as well.

Definitely very high velocity loads and it would be interesting to see how they work on hogs. Given what I've heard about feral hogs I'm guessing a heavier bullet designed for better penetration would be a better option.

Cheers...
 
The upper and lower are the same as for 223. The barrel is not going to blow with a little extra pressure.

oh but it's not the same . The 223 is a very small diameter bullet compared to a 9mm . You need to remove quite a bit of material from a 223 barrel to allow a 9mm to operate in it . The removal of this material makes the barrel weaker . Will it still handle the pressure , maybe but the same they are not .
 
Just for my info, what do you expect to gain from that extra 200 fps? I have 3, 9mms but if I want something bigger, badder, I have some 357 Magnums, and there's always the 10mm. I considered a 9mm carbine, but after some thought I figgered a 230 gr. bullet at bout 1,000-1,100 fps from a 45 ACP will do quite well...

Are hogs really that hard to kill?

ok, now I have to ask, what .45acp gun and load is giving you a 230gr at 1,000-1,100fps???

inquiring minds want to know...;)
 
keep in mind barrel length is going to play a substantial role in your actual measured fps velocities. I load 9mm 124 gr for my 16" bbl Uzi carbine and my near max handgun loads yield about 1310 fps. Uzi's need a robust load to cycle the heavy bolt . I strongly suggest a chronograph if testing handgun caliber loads in rifle barrel lengths.

1000 fps is not difficult with the right powder, even at standard operating pressure.

If you note the article you quoted, even the author there ceded that fast loads of that 230 gn bullet gives some stout recoil that should be managed with upgrades to the firearm. He used a 1911 with a compensator for his testing.

Which is fine, if you set up a pistol to handle the load all is well. But don't be fooled into thinking that a "super powder" that will give you that velocity in safe pressure limits is perfectly fine for your standard pistol. Pressure is dangerous and can blow up firearms. Recoil impulse, even when the pressure is safe, can beat up firearms and shorten their lifespan (sometimes by a great deal). This is why I gave up my .45 super aspirations. I like good triggers. A prudent upgrade to shoot .45 super is a heavier mainspring to help slow the slide down. Heavier mainsprings invariably adds to trigger pull weigh, like it or not. So I decided I liked my sweet trigger more than an extra 100 fps.


Further, there are many loads that will safely give you 900fps with a 230gn .45 projectile... especially if you shoot lead. This loading range is a good balance of power and firearm longevity, IMO.
 
Plus, the author of that article is not good with numbers. He's claiming that going from a load of 13.0 grains to 14.2 grains will increase velocity 10.3% and pressure by only about 6%. So either he has harnessed free energy or he's way off. Basically, with the same 5" standard 45 Auto test barrel length, the dead minimum the pressure will increase is as the square of the ratio of the velocities, which would put it at 22,485 psi. It goes up in proportion to the square of velocity because when you double velocity you halve the barrel time, to the pressure has to accelerate the bullet to twice the velocity in half the time, and that takes four times as much pressure, and four is the square of two. But that simple calculation assumes the ratio of the peak pressure to the muzzle pressure is constant, but in reality, peak pressure climbs faster than muzzle pressure. QuickLOAD, after adjusting the powder parameters and seating depth to meet Ramshot's measured pressure and velocity, and then raising the charge weight to 14.2 grains, does, in fact, come very close to 1078 fps (it gets 1083 fps), and puts the pressure at 23,957 psi. That's probably about right.

The recoil calculation is off, too. QuickLOAD puts it at a whopping 15 ft-lbs and change. I don't think the author used correct muzzle gas velocity. By way of comparison, a 9 lb rifle in 30-06 firing a 150-grain bullet at 2870 fps using IMR4320 has that same recoil energy. Great fun one-handed, I expect.

My load of CFE for Pistol under a RMR 230 FMJ, and not max, will give me that velocity in my pistol caliber carbine. We were talking about a pistol caliber carbine, weren't we?

If you use 4000 fps for the gas velocity you get 14.7 ft lbs of recoil.

If you use 1.5 times the bullet velocity for the gas velocity, you get 11.6 ft lbs of recoil. SAAMI uses the 1.5X factor for handgun ammo.

I don't see any claim of the pressure at 14.2 grains.

Here are some old manuals with pressure listed with Enforcer at different charge weights in the 45 Auto that you might find useful for your calculations. They suggest that your Quickload calculations are off quite a bit.

I believe the OP stated a 9mm AR15. All/most of the 45 ACP data I see is tested in a 5" bbl. My carbine has a 17 1/2" bbl so I figger 1,000-1,100 fps is reachable without going over max., but I haven't shot any over my chrony yet...
